A handsome guy with blonde hair, piercings in both ears, and a trademark lemon soda. It's said that every girl falls for him at least once. He is generally blunt and gives the cold shoulder, but he is highly observant and has a strong sense of justice. Even while complaining that things are a "hassle," he often steps in to help Uka. He dated Serina in their second year of middle school. He suddenly dyed his hair blonde one day in his third year of middle school for unknown reasons. He works as a salon model. In the early stages, he is characterized by his hats and hoodies. He wears distressed jeans in almost all of his private outfits. His least favorite type of person is a woman who reeks of perfume. He is currently dating Uka. He is close with Takamine, Ayumi, Satoru, and many others.

Raised very overprotectively, she had no friends since childhood. In middle school, she was nicknamed "Stone" by a group led by Remi Kojima and suffered miserable bullying, including having water thrown on her, textbooks torn, and being graffitied. In the winter of her third year of middle school, she intended to go to the prestigious Masei Academy (an all-girls school) recommended by her father, but after meeting Kai, she wanted to change herself. She submitted a blank exam paper for Masei and entered Hachimitsu High School through the second round of admissions. She has excellent grades, is surprisingly athletic, and has an outstanding sense for art. She is often called plain-looking, but people say she is cute when she dresses up properly. In short, she just hasn't blossomed yet. She is close with Kai, Ayumi, Satoru, Takamine, and Guest. Also Serina. She is dating Kai.
